139c. Find the coordinates of the point of intersection of the lines. y=1-2x and y=x-5
PLS HELP ASAP
Answers
The coordinates of the point of intersection is equal to (3, 5).
What is a point of intersection?In Mathematics, a point of intersection can be defined as the location on a graph where two (2) lines intersect, meet, or cross each other, which is typically represented as an ordered pair containing the point, x-axis and y-axis.
Next, we would solve the given equations simultaneously to determine the coordinates of the point of intersection as follows:
y = 1 - 2x
y = x - 5
Re-arranging the equation, we have:
y + 2x = 1
y - x = -5
Subtracting, we have:
3x = 6
x = 6/2
x = 3.
For y-coordinate, we have:
y + 2x = 1
y + 2(3) = 1
y + 6 = 1
y = 1 - 6
y = -5.

Supergym is a national chain of gyms. This year, its employees sold 10,412 gym memberships, which turns out to be 52% more than they sold last year. How many memberships did they sell last year?
Answers
The supergym sold 15,826.24 membership last year
How to calculate the number of membership sold ?
This year it's employees sold 10,412
This number is 52% more that they sold last year
The first step is to calculate 52% of 10,412
52/100 × 10,412
= 0.52 × 10412
= 5,414.24
The number of membership sold this year can be calculated as follows
= 5414.24 + 10,412
= 15,826.24
Hence the number of membership they sold last year is 15,826.24

Line equation is 5x+2y=10. The point (-6,7). An equation line through the given point and parallel to the given equation is 5x+2y+16=0.
Given that,
Line equation is 5x+2y=10
The point (-6,7)
We have to find an equation line through the given point and parallel to the given equation, in slope-intercept form.
Take equation 5x+2y=10
2y=10-5x
y=(10-5x)/2
y=5-5/2x
The slope of the equation is -5/2
Now, the slope equation formula is
(y-y₁)=m(x-x₁)
Here,
m is -5/2
x₁=-6
y₁=7
We substitute in the formula
(y-7)=-5/2(x-(-6))
(y-7)=-5/2(x+6)
2(y-7)=-5(x+6)
2y-14=-5x-30
5x+2y=-30+14
5x+2y=-16
5x+2y+16=0
Therefore, an equation line through the given point and parallel to the given equation is 5x+2y+16=0.

Step-by-step explanation:
1 minute / 3 minutes = 1/3
216 feet * 1/3 = 216/3 feet per minute
Answer:
72 feet
Step-by-step explanation:
This question tests on the concept of conversion.

3 minutes = 216 feet
(3÷3) minute = (216 ÷ 3) feet

Write the equation of the line that goes through the point (3,-3) and has a slope of -5/3 (in slope intercept form).
Answers
The equation of the line that goes through the point (3,-3) and has a slope of -5/3 is y=(-5x+6)/3.
What is a slope?In mathematics, line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. The letter m is frequently used to represent a slope; reason for this is unclear, although it is first used in English by O'Brien in 1844, who wrote the equation for a straight line as "y = mx + b," and by Todhunter in 1888, who wrote it as "y = mx + c."
The ratio of "vertical change" to "horizontal change" between (any) two unique points on a line is used to compute slope. The ratio can also be written as quotient ("rise over run"), which produces same number for every two distinct points on the same line. A declining line has negative "rise." The line might be useful, as determined by road surveyor, or it might appear in a diagram that represents a road or a roof as a description or a design.
The slope's absolute value serves as a gauge for line's steepness, incline, or grade. A steeper line is indicated by slope with a higher absolute value. A line can be drawn with one of four directions: upward, downward, horizontal, or vertical.
if we let y = mx + b, where m is the slope and b is the intercept, and y - y1 = m (x - x1), then:
3(y + 3) = - 5 (X - (-3))
3y + 9 = - 5 X + 15
3y = -5 X + 6
y=(-5x+6)/3
Check:
When x = 3, y should equal - 3, so:
Y = (- 5 (3) + 6)/3 = -3

What is the value of z in the system shown below?
x+y+z=6
x + 2y = 5
2x+z = 5
Answers
========================================================
Explanation:
I'll use the substitution method to solve this system of equations.
Solve the third equation for z
2x+z = 5
z = 5-2x
Then solve the second equation for y
x+2y = 5
2y = 5-x
y = (5-x)/2
y = -0.5x+2.5
Plug each of these into the first equation so we can solve for x.
x+y+z = 6
x+(-0.5x+2.5)+(5-2x) = 6
-1.5x+7.5 = 6
-1.5x = 6-7.5
-1.5x = -1.5
x = (-1.5)/(-1.5)
x = 1
Let's use this to find y and z
y = -0.5x+2.5 = -0.5*1+2.5 = 2
z = 5-2x = 5-2*1 = 3
Therefore,
x = 1
y = 2
z = 3
Or we can write it like this: (x,y,z) = (1,2,3)
-------------------
Check:
Plug these values into equation 1 and simplify
x+y+z = 6
1+2+3 = 6
6 = 6
We get the same thing on both sides.
This confirms equation 1.
Repeat for equation 2.
x+2y = 5
1+2*2 = 5
1+4 = 5
5 = 5
This confirms equation 2.
Lastly, plug those values into equation 3
2x+z = 5
2*1+3 = 5
2+3 = 5
5 = 5
Equation 3 is confirmed.
All three equations are true when (x,y,z) = (1,2,3). The solution is fully confirmed.
